| 摘 要： | 为了解决传统电磁环境度量方法中指标提取主观因素多，计算难度大等问题，提出将分形理论应用于电磁环境度量指标计算的方法。首先证明了电磁环境的分形特征，然后提出基于数学形态学的电磁环境分形维数计算方法，并阐述了将电磁环境分形维数作为度量其复杂度指标的意义。对计算结果进行分析，表明该方法能从时间和空间上为区分电磁环境的复杂程度提供多维的信息。

| Abstract: | A novel scale indicator calculation method is introduced based on fractal theory in order to solve the problems of too much subjectivity and great calculation difficulty in indicator extraction by using conventional electromagnetic environment measurement method. After demonstrating the fractal characteristics of the electromagnetic environment, the fractal dimension calculation method based on mathematical morphology is investigated, and then applied to calculating the electromagnetic environment complexity index. The calculation results indicate that this method can provide multidimensional information to distinguish the electromagnetic environment complexity in both space and time. |
